英文摘要	Microporous H-ZSM-5 containing one BrOnsted acid site per asymmetric unit is deliberately chosen to host pyridine, methanol, and ammonia as guest molecules. By using new-generation insitu synchrotron X-ray powder diffraction combined with Rietveld refinement, the slight but significant alteration in scattering parameters of framework atoms modified by the guest molecules enables the user to elucidate their adsorption geometries and interactions with the BrOnsted acid sites in H-ZSM-5 in terms of atomic distances and angles within experimental errors. The conclusion, although demonstrated in the H-ZSM-5, is expected to be transferable to other zeolites. This approach provides a stepping stone towards the rational engineering of molecular interaction(s) with acid sites in zeolitic catalysis.; EPSRC, UK (Oxford); Diamond Light Source Ltd; Office of China Postdoctoral Council; SCI(E); EI; PubMed; ARTICLE; edman.tsang@chem.ox.ac.uk; 20; 5981-5984; 55
